What Coselgi does

Coselgi is a Denmark-headquartered hearing aid brand founded in 1961 and currently owned by WS Audiology, the global hearing aid group formed through the merger of Widex and Sivantos. The company designs, manufactures, and distributes hearing aids and related accessories across more than 30 countries, with regional corporate offices in Denmark (Lynge) and India (New Delhi). Coselgi operates two main product lines, Mojo and Effect, each spanning multiple form factors including Custom in-ear (CIC), Receiver-In-Canal (RIC), and Behind-the-Ear (BTE) styles, addressing a range of hearing loss profiles from mild to severe.

The company sells exclusively through a network of authorized hearing care professionals and audiologists rather than direct-to-consumer, a model that supports professional fitting and adjustment required for medical device efficacy. Pricing is not publicly disclosed and is determined at the point of sale by the authorized professional based on individual patient needs. The brand is explicitly positioned as offering "advanced hearing aids and accessories at competitive prices," occupying a value tier within the WS Audiology portfolio. Coselgi does not sell direct to consumers online; instead, it deploys a multi-language website, an online hearing test tool, and a Shop Finder that funnels prospective customers into the authorized-professional channel for fitting and purchase.

Coselgi is a private entity with 51-100 employees and no public ticker, fundraising activity, or independent ownership structure disclosed. All trademarks, technology platforms, and distribution channels are operated through WS Audiology A/S and its regional entities (e.g., WS Audiology Benelux B.V.). The brand's strategic positioning, R&D access, and geographic footprint are therefore defined and constrained by the parent group's portfolio strategy.

Broad incumbents

• Beltone: Beltone is a long-established hearing aid brand and retail network owned by GN Hearing, serving customers through a franchise-heavy professional model in North America — overlapping with Coselgi's hearing care professional channel strategy.
• Miracle-Ear: Miracle-Ear is a large hearing aid retailer/franchise network in North America offering multiple brands via in-person consultations — comparable to Coselgi's emphasis on professional fitting, though operating primarily through owned retail locations.

Emerging players

• Audicus: Audicus is an online hearing aid retailer offering value-priced hearing aids direct-to-consumer. Comparable to Coselgi in targeting the affordable segment but distinct in its pure-online sales approach versus Coselgi's professional-channel model.
• Eargo: Eargo is a DTC/online hearing aid brand focused on discreet, direct-to-consumer devices — overlapping with Coselgi's affordable-tier and miniaturization-focused product positioning but differentiated by a direct online channel rather than professional fitting.

Direct peers

• Widex: Widex is a premium hearing aid brand of WS Audiology (parent of Coselgi). It serves the same end users and channels as Coselgi, and shares technology and distribution resources, making it the most natural internal benchmark for Coselgi's product and go-to-market approach.
• Starkey: Starkey is a US-based hearing aid manufacturer offering a full line of custom, RIC, and BTE hearing aids distributed through hearing professionals — directly comparable to Coselgi in product breadth, form factors, and professional-channel go-to-market.

• Signia: Signia is a hearing aid brand within WS Audiology (Sivantos lineage), the same parent as Coselgi. It competes in overlapping channels and product categories, making it the closest direct comparison for Coselgi's positioning within the same group.
• ReSound: ReSound is GN Hearing's hearing aid brand, offering CIC, RIC, and BTE styles through professional audiology channels globally — directly comparable to Coselgi's product categories, distribution model, and end customers.
• Oticon: Oticon is the lead hearing aid brand of Demant, offering a broad portfolio across form factors and price tiers, sold through hearing care professionals worldwide. It mirrors Coselgi's professional distribution model and product-line breadth.
